I saw the 100 Burpee challenge on this forum the other day so i decided to give it a go. As the name suggests you do a hundred burpee's jumping as high as you can on each one and time yourself. Ive tried it once so far and my time was 4min20s for the full 100. Hopefully this will improve and now ive got a time to aim for i now feel i will be able to push myself better. Do this and post your time should be good and an added incentive to train harder and get fitter!
